STOVE.

SPECIFICATION forming part of Letters Patent No. 4919,122, dated January'7, 1890.

Application filed February 19, 1889. Serial No. $00,504. (No model.)

T0 all whom, t may concern.-

Be it known that I, GEORGE FRANKLIN HIGGINS, a citizen of the UnitedStates, re-` siding at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Stoves, of whichthe following` is a specification.

The object of my invention is to make a simple, economical,surface-burning stove for either lhard or soft coal; and the inventionconsists in the features and combinations hereinafter described andclaimed.

In the accompanying drawings, Figure l is a side elevation, in section,of my improved stove; and Fig. 2, a front elevation, in section, of thesame. i

A is a iire-box, and a an ash-door therein; B, a combustion-chamber',l), a fuel-door therein, and b a deflecting-plate at the top and side ofthe combuStien-chamber; C, an inlet for introducing cold air into thefire-box or combustion-chamber, and c a cap forming a lip to prevent thefuel from stopping the inflow-of cold air; D, ahot box; E, a flue orchamber for introducing atmospheric air, communicating with the hot box;F, a sinuous flue for the heated products of combustion, formed in partby the deflectors of the combustionchamber, and f an outlet therefrom;and G, a collar forming a register to permit the warm air to escape forheating purposes.

My improved stove comprises, essentially, a fire-box,combuStien-chamber, iiues, het box, and inlets and outlets so arrangedwith reference to each other that atmospheric air is heated by directintroduction into the het box and then allowed to escape throughregistersinto the room desired to be warmed. The fire-box, the upperpart of which I call a combustionchamber, is in the usual form. Onepeculiarity ofthe combustion-chamber consists in providing the air inletor inlets with a cap, preferably forming a lip, to prevent the in Iiowof air from being stopped or choked by the fuel. The air-inlet havingthis cap or lip cannot be choked to an extent that will intcrfere withthe iniiow of the atmospheric air necessary for combustion. I prefer tohave four of these inlets-two at the front and two at the back; but moreor less may be used, as desired. I also prefer to have them at oppositesides in the combustion-chamber, with their caps pointing inwardlytoward -each other, so that the atmospheric air coming in from oppositesides will be directed and passed over the fire to cause the gas to burnfrom the top or below the top of the coal, and not from a pointmaterially above it.

Another peculiarity of the combustionchamber consists in so forming itstop and side as to deflect the heated air or products of combustion andcause them to be carried down and around in a sinuous iiue F, asindicated by arrows. The top and side of the combustiou-chamber beingthus formed operate to deflect and carry the heated air or products ofcombustion down to a very low point, so that after leaving this pointthey will in their upward progress pass along almost the entire lengthof the iiue or chamber employed to introduce atmospheric air for heatingor warming purposes. In this way, by extending the top of thecombustionchamber to a point beyond its back and then deflecting andextending it down to near the bottom, a continuous flue is formed; or,in other words, the flue at the side of the combustion-chamber isdivided vertically, and thus made into two fines, or, as I prefer tocall it, a double flue. The heated air or products of combustion descendin that part of this flue next to the combustion-chamber, and afterwardascend in that part next to the cold-air flue. The atmospheric airdesired to be heated and introduced into the room for warming purposesfirst comes in at or near the bottom, and then passes up through the dueor chamber E at the back of the stove and into the hot boX near the top,from which, after becoming sufficiently heated, it is allowed to escapeby registers or otherwise into the room desired tobc warmed. Theposition of this back flue or chamber with reference to the hot-air flueat its side and the hot box at its top is such as to give the advantagesof both a radiating and a circulating stove in one construction, andthis, too, in a very simple and efficient way.

As already stated, in my improved stove the heated products ofcombustion are brought down to a point near the bottom and then allowedto pass up by the side of the air-cham- IOO and operation gives agreater' capacity for heating and radiation, and, as just suggested,enables the atmospheric air in the back cham ber and hot box to beheated by what is now useless, lost, or Waste heat.

I do not herein claim means forheating atmospherie air before itsintroduction into the combustion-chamber, thesame being the subject ofYVanother appliealionrled by me Octo\ ber 8, 1889, Serial No. 326,315.

y I claim- A stove having a fire-pot, a iiue leading therefrom andextending` downward behind the fire-pot to the base of the stove, thenceupward and over the top of the fire-pot to the front of the stove, andfinally to an exit-opening at the rear of the stove, and a hot-air flueleading from an opening in the base and winding contiguously to thatportion of the smoke-Hue which extends upward from its base andcommunicating with an opening in the topof the stove, substantially asdescribed.
